[Building Sakai] Strangeness in http://nightly2.sakaiproject.org:8082/portal's rwiki

[Jean-Francois Leveque]

Hi all,

I was trying something on nightly2's sakai/trunk on Oracle and found 
unexpected results.

http://nightly2.sakaiproject.org/logs/tomcat-nightly-oracle/catalina.out 
is complaining a lot about UTF-8:
> Warning:  The encoding 'UTF-8' is not supported by the Java runtime.
> Warning: encoding "UTF-8" not supported, using UTF-8

And also about markup on a post:
> 2014-10-07 10:03:08,443  WARN http-bio-8082-exec-3 org.sakaiproject.portal.charon.handlers.SiteHandler - It is tacky to return markup on a POST CTI=sakai.rwiki URL=http://nightly2.sakaiproject.org:8082/portal/site/297eb641-f852-4f06-9e08-980d0228f5e4/tool/c4d06e64-9803-449f-952e-05f793354c13?

Maybe this has something to do with rwiki's search not working. Is there 
a known issue in trunk?

This might be related to the following sakai/trunk on Oracle logs:
> 2014-10-07 08:08:33,080 WARN localhost-startStop-1 org.sakaiproject.springframework.orm.hibernate.AddableSessionFactoryBean - Unsuccessful schema statement: create index irwikiobject_name on rwikiobject (name)

Any idea?

Cheers,
